I have a 5770 in Slot 1, and an Apricorn Velocity Solo X2 in Slot 2. I decided to put an second SSD in, and bought another Apricorn for it. But as I'm putting it in, I realized that it's going in a 1.0 slot in Slot 3, right?? I think I need a Velocity DUO to have two separate bootable SSDs in one PCIe 2.0 slot, right?

Thanks!
 
Slots 3 and 4 are PCIe 1.1, 4x, but will support the 16x width.

Here's a link to Apple's PDF manual for more info. See page 60.

Thanks.....so I'll get slower speeds using the 1.1 slots, right? I think I need a Velocity Duo.

Yes, it'll always operate at the speed of the slowest component. Like putting a USB 3.0 HD into a USB 2.0 port, it'll work but on 2.0 speeds.
 
OK Mods pay up! I think I read some MR small print that and I quote, "If ever there are two or more users that have identical join dates on line at the same time in the same thread they will receive the latest Apple computer of their choice"! I noticed that "tech4all" and OS6-OSX have identical join dates! Please send one each of these to today's winners:p!

HAHA, I noticed that too! What a coincidence! :cool:
 
Thanks sgain....got it.

So is the Duo what I need to have two separate boot SSDs in one slot? Or does that card combine both SSDs into one drive?
